I don't agree that it would be a nightmare for the hotel. You check in a guest, and when they are done you reimage the computer off a CD or whatever. The maid could do it, pop in the CD while she's vaccuming the computer reimages itself, and then she takes it out when she's done.

Would I do banking or anything sensitive on it? Of course not, but I wouldn't do that in the business center either and lots of people do. Would I surf the web all night long and the rest for $10? If I'm traveling alone, without a doubt.
